BACKGROUND OF THE INVENTION

I. Technical Field of the Invention

The present invention relates to the field of corn breeding. Inparticular, the invention relates to inbred corn seed and plantsdesignated GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4,01ASB1, 01IBH2, NL054B and FBMU, and derivatives and tissue cultures ofsuch inbred plants.

II. Description of the Background Art

The goal of field crop breeding is to combine various desirable traitsin a single variety/hybrid. Such desirable traits include greater yield,better stalks, better roots, resistance to insecticides, pests, anddisease, tolerance to heat and drought, reduced time to crop maturity,better agronomic quality, and uniformity in germination times, standestablishment, growth rate, maturity, and fruit size.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same plant. A plant cross-pollinates if pollen comes to it from aflower on a different plant.

Corn plants (Zea mays L.) can be bred by both self-pollination andcross-pollination. Both types of pollination involve the corn plant'sflowers. Corn has separate male and female flowers on the same plant,located on the tassel and the ear, respectively. Natural pollinationoccurs in corn when wind blows pollen from the tassels to the silks thatprotrude from the tops of the ears.

Plants that have been self-pollinated and selected for type over manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny, a homozygous plant. A crossbetween two such homozygous plants produce a uniform population ofhybrid plants that are heterozygous for many gene loci. Conversely, across of two plants each heterozygous at a number of gene loci producesa population of hybrid plants that differ genetically and are notuniform. The resulting non-uniformity make performance unpredictable.

The development of uniform corn plant hybrids requires the developmentof homozygous inbred plants, the crossing of these inbred plants, andthe evaluation of the crosses. Pedigree breeding and recurrent selectionbreeding methods are used to develop inbred plants from breedingpopulations. Those breeding methods combine the genetic backgrounds fromtwo or more inbred plants or various other broad-based sources intobreeding pools from which new inbred plants are developed by selfing andselection of desired phenotypes. The new inbreds are crossed with otherinbred plants and the hybrids from these crosses are evaluated todetermine which of those have commercial potential.

The pedigree breeding method for single-gene traits involves crossingtwo genotypes. Each genotype can have one or more desirablecharacteristics lacking in the other; or, each genotype can complementthe other. If the two original parental genotypes do not provide all ofthe desired characteristics, other genotypes can be included in thebreeding population. Superior plants that are the products of thesecrosses are selfed and selected in successive generations. Eachsucceeding generation becomes more homogeneous as a result ofself-pollination and selection. Typically, this method of breedinginvolves five or more generations of selfing and selection: S₁→S₂;S₂→S₃; S₃→S₄; S₄→S₅, etc. After at least five generations, the inbredplant is considered genetically pure.

Backcrossing can also be used to improve an inbred plant. Backcrossingtransfers a specific desirable trait from one inbred or source to aninbred that lacks that trait. This can be accomplished for example byfirst crossing a superior inbred (A) (recurrent parent) to a donorinbred (non-recurrent parent), which carries the appropriate gene(s) forthe trait in question. The progeny of this cross are then mated back tothe superior recurrent parent (A) followed by selection in the resultantprogeny for the desired trait to be transferred from the non-recurrentparent. After five or more backcross generations with selection for thedesired trait, the progeny are heterozygous for loci controlling thecharacteristic being transferred, but are like the superior parent formost or almost all other genes. The last backcross generation would beselfed to give pure breeding progeny for the gene(s) being transferred.

A single cross hybrid corn variety is the cross of two inbred plants,each of which has a genotype which complements the genotype of theother. The hybrid progeny of the first generation is designated F₁.Preferred F₁ hybrids are more vigorous than their inbred parents. Thishybrid vigor, or heterosis, is manifested in many polygenic traits,including markedly improved higher yields, better stalks, better roots,better uniformity and better insect and disease resistance. In thedevelopment of hybrids only the F₁ hybrid plants are sought. An F₁single cross hybrid is produced when two inbred plants are crossed. Adouble cross hybrid is produced from four inbred plants crossed in pairs(A×B and C×D) and then the two F₁ hybrids are crossed again (A×B)×(C×D).

The development of a hybrid corn variety involves three steps: (1) theselection of plants from various germplasm pools; (2) the selfing of theselected plants for several generations to produce a series of inbredplants, which, although different from each other, each breed true andare highly uniform; and (3) crossing the selected inbred plants withunrelated inbred plants to produce the hybrid progeny (F₁). During theinbreeding process in corn, the vigor of the plants decreases. Vigor isrestored when two unrelated inbred plants are crossed to produce thehybrid progeny (F₁). An important consequence of the homozygosity andhomogeneity of the inbred plants is that the hybrid between any twoinbreds is always the same. Once the inbreds that give a superior hybridhave been identified, hybrid seed can be reproduced indefinitely as longas the homogeneity of the inbred parents is maintained. Conversely, muchof the hybrid vigor exhibited by F₁ hybrids is lost in the nextgeneration (F₂). Consequently, seed from hybrid varieties is not usedfor planting stock. It is not generally beneficial for farmers to saveseed of F₁ hybrids. Rather, farmers purchase F₁ hybrid seed for plantingevery year.

North American farmers plant over 70 million acres of corn at thepresent time and there are extensive national and internationalcommercial corn breeding programs. A continuing goal of these cornbreeding programs is to develop high-yielding corn hybrids that arebased on stable inbred plants that maximize the amount of grain producedand minimize susceptibility to environmental stresses. To accomplishthis goal, the corn breeder must select and develop superior inbredparental plants for producing hybrids.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides corn plants designated,separately, GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4,01ASB1, 01IBH2, NL054B and FBMU. Also provided are corn plants havingthe functional and morphological characteristics of corn plants GMLEA,6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2,NL054B or FBMU, as exemplified by corn plants having all thephysiological and morphological characteristics of corn plants GMLEA,6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2,NL054B or FBMU.

The inbred corn plants of the invention may further comprise, or have, acytoplasmic factor that is capable of conferring male sterility. Partsof the corn plants of the present invention are also provided, such as,e.g., pollen obtained from an inbred plant and an ovule of the inbredplant.

The invention also concerns seed of the corn plant WDDQ1 which has beendeposited with the ATCC. The invention thus provides inbred corn seeddesignated WDDQ1 and having ATCC Accession No. PTA-6252.

The inbred corn seed of the invention may be provided as essentiallyhomogeneous populations of inbred corn seed designated GMLEA, 6F905,91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B orFBMU. Essentially homogeneous populations of inbred seed are those thatconsist essentially of the particular inbred seed and are generallypurified free from substantial numbers of other seed, so that the inbredseed forms between about 90% and about 100% of the total seed, andpreferably, between about 95% and about 100% of the total seed. Mostpreferably, an essentially homogeneous population of inbred corn seedwill contain between about 98.5%, 99%, 99.5% and about 100% of inbredseed, as measured by seed grow outs.

In any event, even if a population of inbred corn seed was found, forsome reason, to contain about 50%, or even about 20% or 15% of inbredseed, this would still be distinguished from the small fraction ofinbred seed that may be found within a population of hybrid seed, e.g.,within a bag of hybrid seed. In such a bag of hybrid seed offered forsale, the Governmental regulations require that the hybrid seed be atleast about 95% of the total seed. In the practice of the presentinventors, the hybrid seed generally forms at least about 97% of thetotal seed. In the most preferred practice of the inventors, the femaleinbred seed that may be found within a bag of hybrid seed will be about1% of the total seed, or less, and the male inbred seed that may befound within a bag of hybrid seed will be negligible, i.e., will be onthe order of about a maximum of 1 per 100,000, and usually less thanthis value.

The populations of inbred corn seed of the invention are furtherparticularly defined as being essentially free from hybrid seed. Theinbred seed populations may be separately grown to provide essentiallyhomogeneous populations of inbred corn plants designated GMLEA, 6F905,91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B orFBMU.

The tissueculture will preferably be capable of regenerating plants having thephysiological and morphological characteristics of one of the foregoinginbred corn plants, and of regenerating plants having substantially thesame genotype as one of the foregoing inbred corn plants. Preferably,the regenerable cells in such tissue cultures will be embryos,protoplasts, meristematic cells, pollen, leaves, anthers, roots, roottips, silk, flowers, kernels, ears, cobs, husks or stalks. Stillfurther, the present invention provides corn plants regenerated from oneof the tissue cultures of the invention.

In another aspect, the present invention provides for single geneconverted plants of GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1,85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU. The single transferredgene may preferably be a dominant or recessive allele. Preferably, thesingle transferred gene will confer such traits as male sterility,herbicide resistance, insect resistance, resistance for bacterial,fungal, or viral disease, male fertility, enhanced nutritional quality,and industrial usage.

In yet another aspect, the present invention provides processes forpreparing corn seed or plants, which processes generally comprisecrossing a first parent corn plant with a second parent corn plant,wherein at least one of the first or second parent corn plants is theinbred corn plant designated GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU. These processesmay be further exemplified as processes for preparing hybrid corn seedor plants, wherein a first inbred corn plant is crossed with a second,distinct inbred corn plant to provide a hybrid that has, as one of itsparents, the inbred corn plant GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU.

In a preferred embodiment, crossing comprises planting, in pollinatingproximity, seeds of the first and second parent corn plant, andpreferably, seeds of a first inbred corn plant and a second, distinctinbred corn plant; cultivating or growing the seeds of said first andsecond parent corn plants into plants that bear flowers; emasculatingthe male flowers of the first or second parent corn plant, i.e.,treating the flowers so as to prevent pollen production, in order toproduce an emasculated parent corn plant; allowing naturalcross-pollination to occur between the first and second parent cornplants; and harvesting the seeds from the emasculated parent corn plant.Where desired, the harvested seed is grown to produce a corn plant orhybrid corn plant.

The present invention also provides corn seed and plants produced by aprocess that comprises crossing a first parent corn plant with a secondparent corn plant, wherein at least one of the first or second parentcorn plants is the inbred corn plant designated GMLEA, 6F905, 91CSV-1,91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU.

It should be noted here that although the present invention provides 12inbreds, the details concerning only 10 exemplary hybrids are set forthherein. This results from the crossing of certain of the claimed inbredswith other inbreds of this invention. Four hybrids are disclosed hereinthat have both parents from the presently claimed inbreds, namely DK706,DK446, DK604, and DK527. Also, the inbred 01IBH2 is employed to generatethree different, particularly successful hybrids. Accounting for thesevarious combinations results in the ten hybrids disclosed herein thathave commercially advantageous features. Table 30 is provided herein forinstant cross-reference of the disclosed inbreds and exemplary hybrids.

In yet a further aspect, the invention provides inbred geneticcomplements of corn plants designated, separately, GMLEA, 6F905,91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054Band FBMU. The phrase “genetic complement” is used to refer to theaggregate of nucleotide sequences, the expression of which sequencesdefines the phenotype of, in the present case, a corn plant, or a cellor tissue of that plant. An inbred genetic complement thus representsthe genetic make up of an inbred cell, tissue or plant, and a hybridgenetic complement represents the genetic make up of a hybrid cell,tissue or plant. The invention thus provides corn plant cells that havea genetic complement in accordance with the inbred corn plant cellsdisclosed herein, and plants, seeds and diploid plants containing suchcells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.Thus such corn plant cells may be defined as having an RFLP geneticmarker profile in accordance with the profile shown in Table 52, Table53, Table 54, Table 55, Table 56, Table 57, Table 58, Table 59, Table60, Table 61, Table 62 or Table 63; or a genetic isozyme typing profilein accordance with the profile shown in Table 64, Table 65, Table 66,Table 67, Table 68, Table 69, Table 70, Table 71, Table 72, Table 73,Table 74 or Table 75; or having both an RFLP genetic marker profile anda genetic isozyme typing profile in accordance with the profiles shownin Tables 52 and 64; Tables 53 and 65; Tables 54 and 66; Tables 55 and67; Tables 56 and 68; Tables 57 and 69; Tables 58 and 70; Tables 59 and71; Tables 60 and 72; Tables 61 and 73; Tables 62 and 74; or as shown inboth Tables 63 and 75.

In another aspect, the present invention provides hybrid geneticcomplements, as represented by corn plant cells, tissues, plants andseeds, formed by the combination of a haploid genetic complement of aninbred corn plant of the invention with a haploid genetic complement ofa second corn plant, preferably, another, distinct inbred corn plant.

The origin and breeding history of inbred plant GMLEA can be summarizedas follows:

Winter 1982 The cross of LH38 to the cross between MO17HT.75802 was made(nursery row numbers 215 and 216). Winter 1983 LH38, a line developed byHolden's Foundation Seeds, Inc., was crossed to the single crossdescribed above (equivalent to S₁ generation) (nursery row numbers 35and 36). Summer 1984 The S₁ was grown and plants were self-pollinated(nursery row number 1309-1312). Winter 1985 S₂ ears were grownear-to-row and self-pollinated (nursery rows 85-90). Summer 1985 S₃ earswere grown ear-to-row and self-pollinated (nursery rows 2415-2418).Winter 1986 S₄ ears were grown ear-to-row and self-pollinated (nurseryrows 98-101). Summer 1986 S₅ ears were grown ear-to-row andself-pollinated (nursery rows 4491-4493). Summer 1987 S₆ ears were grownear-to-row and self-pollinated (nursery rows 5247-5248).

A. Origin and Breeding History

Inbred plant WDDQ1 was derived from a cross between inbred plant LH132(a proprietary line of Holden's Foundation Seeds, Inc.) and a lineselected from 3378 (a hybrid developed by Pioneer Hi-BredInternational).

WDDQ1 shows uniformity and stability within the limits of environmentalinfluence for the traits described hereinafter in Table 12. WDDQ1 hasbeen self-pollinated and ear-rowed a sufficient number of generationswith careful attention paid to uniformity of plant type to ensurehomozygosity and phenotypic stability. No variant traits have beenobserved or are expected in WDDQ1.

A deposit of 2500 seeds of the plant designated WDDQ1 has been made withthe American Type Culture Collection (ATCC), 10801 University Blvd.,Manassas, Va. on Oct. 11, 2004. Those deposited seeds have been assignedAccession No. PTA-6252. This deposit was made in accordance with theterms and provisions of the Budapest Treaty relating to deposit ofmicroorganisms and is made for a term of at least thirty (30) years andat least five (05) years after the most recent request for thefurnishing of a sample of the deposit was received by the depository, orfor the effective term of the patent, whichever is longer, and will bereplaced if it becomes non-viable during that period.

Inbred corn plants can be reproduced by planting such inbred seeds,growing the resulting corn plants under self-pollinating orsib-pollinating conditions with adequate isolation using standardtechniques well known to an artisan skilled in the agricultural arts.Seeds can be harvested from such a plant using standard, well knownprocedures.

The origin and breeding history of inbred plant WDDQ1 can be summarizedas follows:

Summer 1987 The backcross of LH132 and a selection from the hybridPioneer 3378 was grown and plants were selfed. The recurrent parent inthe backcross was LH132. LH132 is a proprietary line of Holden'sFoundation Seeds, Inc. Summer 1988 BC₁S₁ ears were grown (nursery rows326-50). Winter 1988-89 BC₁S₂ ears were grown (nursery rows 435-94).Summer 1989 BC₁S₃ ears were grown (nursery rows 222-20). Winter 1989-90BC₁S₄ ears were grown (nursery rows 99-92). Summer 1990 BC₁S₅ ears weregrown. The seed was assigned the inbred code WDDQ1 (nursery rows223-44).

A. Origin and Breeding History

Inbred plant FBMU was derived from the cross between two inbredsdesignated PB80 and 4676A. PB80 and 4676A are both proprietary inbredsof DEKALB Genetics Corporation.

FBMU shows uniformity and stability within the limits of environmentalinfluence for the traits described hereinafter in Table 24. FBMU hasbeen self-pollinated and ear-rowed a sufficient number of generationswith careful attention paid to uniformity of plant type to ensurehomozygosity and phenotypic stability. No variant traits have beenobserved or are expected in FBMU.

Inbred corn plants can be reproduced by planting such inbred seeds,growing the resulting corn plants under self-pollinating orsib-pollinating conditions with adequate isolation using standardtechniques well known to an artisan skilled in the agricultural arts.Seeds can be harvested from such a plant using standard, well knownprocedures.

The origin and breeding history of inbred plant FBMU can be summarizedas follows:

Summer 1982 The cross PB80.4676A was made. PB80 and 4676A are bothproprietary inbreds of DEKALB Genetics Corporation. Winter 1983 S₀ seedwas grown and self-pollinated (nursery row 770). Summer 1983 S₁ earswere grown ear-to-row (nursery rows 701-740). Summer 1984 S₂ ears weregrown ear-to-row. Summer 1985 S₃ ears were grown ear-to-row. Summer 1986S₄ ears were grown ear-to-row. Summer 1987 S₅ ears were grownear-to-row. Bulked S₆ seed was assigned the inbred code FBMU. Summer1988 FBMU was increased (nursery rows 338-342).

Single Gene Conversions

When the term inbred corn plant is used in the context of the presentinvention, this also includes any single gene conversions of thatinbred. The term single gene converted plant as used herein refers tothose corn plants which are developed by a plant breeding techniquecalled backcrossing wherein essentially all of the desired morphologicaland physiological characteristics of an inbred are recovered in additionto the single gene transferred into the inbred via the backcrossingtechnique. Backcrossing methods can be used with the present inventionto improve or introduce a characteristic into the inbred. The termbackcrossing as used herein refers to the repeated crossing of a hybridprogeny back to one of the parental corn plants for that inbred. Theparental corn plant which contributes the gene for the desiredcharacteristic is termed the nonrecurrent or donor parent. Thisterminology refers to the fact that the nonrecurrent parent is used onetime in the backcross protocol and therefore does not recur. Theparental corn plant to which the gene or genes from the nonrecurrentparent are transferred is known as the recurrent parent as it is usedfor several rounds in the backcrossing protocol (Poehlman & Sleper,1994; Fehr, 1987). In a typical backcross protocol, the original inbredof interest (recurrent parent) is crossed to a second inbred(nonrecurrent parent) that carries the single gene of interest to betransferred. The resulting progeny from this cross are then crossedagain to the recurrent parent and the process is repeated until a cornplant is obtained wherein essentially all of the desired morphologicaland physiological characteristics of the recurrent parent are recoveredin the converted plant, in addition to the single transferred gene fromthe nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalinbred. To accomplish this, a single gene of the recurrent inbred ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphological,constitution of the original inbred. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross, one ofthe major purposes is to add some commercially desirable, agronomicallyimportant trait to the plant. The exact backcrossing protocol willdepend on the characteristic or trait being altered to determine anappropriate testing protocol. Although backcrossing methods aresimplified when the characteristic being transferred is a dominantallele, a recessive allele may also be transferred. In this instance itmay be necessary to introduce a test of the progeny to determine if thedesired characteristic has been successfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new inbred but that can be improvedby backcrossing techniques. Examples of these traits include but are notlimited to, male sterility, waxy starch, herbicide resistance,resistance for bacterial, fungal, or viral disease, insect resistance,male fertility, enhanced nutritional quality, and industrial usage.These genes are generally inherited through the nucleus. Some knownexceptions to this are the genes for male sterility, some of which areinherited cytoplasmically, but still act as single gene traits. Severalof these single gene traits are described in U.S. Ser. No. 07/113,561,filed Aug. 25, 1993, the disclosure of which is specifically herebyincorporated by reference.

Direct selection may be applied where the single gene acts as a dominanttrait. An example might be the herbicide resistance trait. For thisselection process, the progeny of the initial cross are sprayed with theherbicide prior to the backcrossing. The spraying eliminates any plantswhich do not have the desired herbicide resistance characteristic, andonly those plants which have the herbicide resistance gene are used inthe subsequent backcross. This process is then repeated for alladditional backcross generations.

The waxy characteristic is an example of a recessive trait. In thisexample, the progeny resulting from the first backcross generation (BC1)must be grown and selfed. A test is then run on the selfed seed from theBC1 plant to determine which BC1 plants carried the recessive gene forthe waxy trait. In other recessive traits, additional progeny testing,for example growing additional generations such as the BC1S1 may berequired to determine which plants carry the recessive gene.

XVII. Origin and Breeding History of an Exemplary Single Gene ConvertedPlant

85DGD1 MLms is a single gene conversion of 85DGD1 to cytoplasmic malesterility. 85DGD1 MLms was derived using backcross methods. 85DGD1 (aproprietary inbred of DEKALB Genetics Corporation) was used as therecurrent parent and MLms, a germplasm source carrying ML cytoplasmicsterility, was used as the nonrecurrent parent. The breeding history ofthe single gene converted inbred 85DGD1 MLms can be summarized asfollows:

Tissue Culture and in vitro Regeneration of Corn Plants

A further aspect of the invention relates to tissue culture of cornplants designated, separately, GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU. As used herein,the term “tissue culture” indicates a composition comprising isolatedcells of the same or a different type or a collection of such cellsorganized into parts of a plant. Exemplary types of tissue cultures areplant protoplast, plant calli, plant clumps, and plant cells that areintact in plants or parts of plants, such as embryos, pollen, flowers,kernels, ears, cobs, leaves, husks, stalks, roots, root tips, anthers,silk and the like. In a preferred embodiment, tissue culture is embryos,protoplast, meristematic cells, pollen, leaves or anthers. Means forpreparing and maintaining plant tissue culture are well known in theart. By way of example, a tissue culture comprising organs such astassels or anthers, has been used to produce regenerated plants. (See,U.S. patent application Ser. No. 07/992,637, filed Dec. 18, 1992 andSer. No. 07/995,938, filed Dec. 21, 1992, now issued as U.S. Pat. No.5,322,789, issued Jun. 21, 1994, the disclosures of which areincorporated herein by reference).

A. Tassel/Anther Culture

Tassels contain anthers which in turn enclose microspores. Microsporesdevelop into pollen. For anther/microspore culture, if tassels are theplant composition, they are preferably selected at a stage when themicrospores are uninucleate, that is, include only one, rather than 2 or3 nuclei. Methods to determine the correct stage are well known to thoseskilled in the art and include mitramycin fluorescent staining (Pace etal., 1987), trypan blue (preferred) and acetocarmine squashing. Themid-uninucleate microspore stage has been found to be the developmentalstage most responsive to the subsequent methods disclosed to ultimatelyproduce plants.

Although microspore-containing plant organs such as tassels cangenerally be pretreated at any cold temperature below about 25° C., arange of 4 to 25° C. is preferred, and a range of 8 to 14° C. isparticularly preferred. Although other temperatures yield embryoids andregenerated plants, cold temperatures produce optimum response ratescompared to pretreatment at temperatures outside the preferred range.Response rate is measured as either the number of embryoids or thenumber of regenerated plants per number of microspores initiated inculture.

Although not required, when tassels are employed as the plant organ, itis generally preferred to sterilize their surface. Following surfacesterilization of the tassels, for example, with a solution of calciumhypochloride, the anthers are removed from about 70 to 150 spikelets(small portions of the tassels) and placed in a preculture orpretreatment medium. Larger or smaller amounts can be used depending onthe number of anthers.

When one elects to employ tassels directly, tassels are preferablypretreated at a cold temperature for a predefined time, preferably at10° C. for about 4 days. After pretreatment of a whole tassel at a coldtemperature, dissected anthers are further pretreated in an environmentthat diverts microspores from their developmental pathway. The functionof the preculture medium is to switch the developmental program from oneof pollen development to that of embryoid/callus development. Anembodiment of such an environment in the form of a preculture mediumincludes a sugar alcohol, for example mannitol or sorbitol, inositol orthe like. An exemplary synergistic combination is the use of mannitol ata temperature of about 10° C. for a period ranging from about 10 to 14days. In a preferred embodiment, 3 ml of 0.3 M mannitol combined with 50mg/l of ascorbic acid, silver nitrate and colchicine is used forincubation of anthers at 10° C. for between 10 and 14 days. Anotherembodiment is to substitute sorbitol for mannitol. The colchicineproduces chromosome doubling at this early stage. The chromosomedoubling agent is preferably only present at the preculture stage.

It is believed that the mannitol or other similar carbon structure orenvironmental stress induces starvation and functions to forcemicrospores to focus their energies on entering developmental stages.The cells are unable to use, for example, mannitol as a carbon source atthis stage. It is believed that these treatments confuse the cellscausing them to develop as embryoids and plants from microspores.Dramatic increases in development from these haploid cells, as high as25 embryoids in 10⁴ microspores, have resulted from using these methods.

In embodiments where microspores are obtained from anthers, microsporescan be released from the anthers into an isolation medium following themannitol preculture step. One method of release is by disruption of theanthers, for example, by chopping the anthers into pieces with a sharpinstrument, such as a razor blade, scalpel or Waring blender. Theresulting mixture of released microspores, anther fragments andisolation medium are then passed through a filter to separatemicrospores from anther wall fragments. An embodiment of a filter is amesh, more specifically, a nylon mesh of about 112 μm pore size. Thefiltrate which results from filtering the microspore-containing solutionis preferably relatively free of anther fragments, cell walls and otherdebris.

In a preferred embodiment, isolation of microspores is accomplished at atemperature below about 25° C. and, preferably at a temperature of lessthan about 15° C. Preferably, the isolation media, dispersing tool(e.g., razor blade) funnels, centrifuge tubes and dispersing container(e.g., petri dish) are all maintained at the reduced temperature duringisolation. The use of a precooled dispersing tool to isolate maizemicrospores has been reported (Gaillard et al., 1991).

Where appropriate and desired, the anther filtrate is then washedseveral times in isolation medium. The purpose of the washing andcentrifugation is to eliminate any toxic compounds which are containedin the non-microspore part of the filtrate and are created by thechopping process. The centrifugation is usually done at decreasing spinspeeds, for example, 1000, 750, and finally 500 rpms.

The result of the foregoing steps is the preparation of a relativelypure tissue culture suspension of microspores that are relatively freeof debris and anther remnants.

To isolate microspores, an isolation media is preferred. An isolationmedia is used to separate microspores from the anther walls whilemaintaining their viability and embryogenic potential. An illustrativeembodiment of an isolation media includes a 6 percent sucrose or maltosesolution combined with an antioxidant such as 50 mg/l of ascorbic acid,0.1 mg/l biotin and 400 mg/l of proline, combined with 10 mg/l ofnicotinic acid and 0.5 mg/l AgNO₃. In another embodiment, the biotin andproline are omitted.

An isolation media preferably has a higher antioxidant level where usedto isolate microspores from a donor plant (a plant from which a plantcomposition containing a microspore is obtained) that is field grown incontrast to greenhouse grown. A preferred level of ascorbic acid in anisolation medium is from about 50 mg/l to about 125 mg/l and, morepreferably from about 50 mg/l to about 100 mg/l.

One can find particular benefit in employing a support for themicrospores during culturing and subculturing. Any support thatmaintains the cells near the surface can be used. The microsporesuspension is layered onto a support, for example by pipetting. Thereare several types of supports which are suitable and are within thescope of the invention. An illustrative embodiment of a solid support isa TRANSWELL® culture dish. Another embodiment of a solid support fordevelopment of the microspores is a bilayer plate wherein liquid mediais on top of a solid base. Other embodiments include a mesh or amillipore filter. Preferably, a solid support is a nylon mesh in theshape of a raft. A raft is defined as an approximately circular supportmaterial which is capable of floating slightly above the bottom of atissue culture vessel, for example, a petri dish, of about a 60 or 100mm size, although any other laboratory tissue culture vessel willsuffice. In an illustrative embodiment, a raft is about 55 mm indiameter.

Culturing isolated microspores on a solid support, for example, on a 10μm pore nylon raft floating on 2.2 ml of medium in a 60 mm petri dish,prevents microspores from sinking into the liquid medium and thusavoiding low oxygen tension. These types of cell supports enable theserial transfer of the nylon raft with its associatedmicrospore/embryoids ultimately to full strength medium containingactivated charcoal and solidified with, for example, GELRITE™(solidifying agent). The charcoal is believed to absorb toxic wastes andintermediaries. The solid medium allows embryoids to mature.

The liquid medium passes through the mesh while the microspores areretained and supported at the medium-air interface. The surface tensionof the liquid medium in the petri dish causes the raft to float. Theliquid is able to pass through the mesh: consequently, the microsporesstay on top. The mesh remains on top of the total volume of liquidmedium. An advantage of the raft is to permit diffusion of nutrients tothe microspores. Use of a raft also permits transfer of the microsporesfrom dish to dish during subsequent subculture with minimal loss,disruption or disturbance of the induced embryoids that are developing.The rafts represent an advantage over the multi-welled TRANSWELL®plates, which are commercially available from COSTAR, in that thecommercial plates are expensive. Another disadvantage of these plates isthat to achieve the serial transfer of microspores to subsequent media,the membrane support with cells must be peeled off the insert in thewells. This procedure does not produce as good a yield nor as efficienttransfers, as when a mesh is used as a vehicle for cell transfer.

The culture vessels can be further defined as either (1) a bilayer 60 mmpetri plate wherein the bottom 2 ml of medium are solidified with 0.7percent agarose overlaid with 1 mm of liquid containing the microspores;(2) a nylon mesh raft wherein a wafer of nylon is floated on 1.2 ml ofmedium and 1 ml of isolated microspores is pipetted on top; or (3)TRANSWELL® plates wherein isolated microspores are pipetted ontomembrane inserts which support the microspores at the surface of 2 ml ofmedium.

After the microspores have been isolated, they are cultured in a lowstrength anther culture medium until about the 50 cell stage when theyare subcultured onto an embryoid/callus maturation medium. Medium isdefined at this stage as any combination of nutrients that permit themicrospores to develop into embryoids or callus. Many examples ofsuitable embryoid/callus promoting media are well known to those skilledin the art. These media will typically comprise mineral salts, a carbonsource, vitamins, growth regulations. A solidifying agent is optional. Apreferred embodiment of such a media is referred to by the inventor asthe “D medium” which typically includes 6N1 salts, AgNO₃ and sucrose ormaltose.

In an illustrative embodiment, 1 ml of isolated microspores are pipettedonto a 10 μm nylon raft and the raft is floated on 1.2 ml of medium “D”,containing sucrose or, preferably maltose. Both calli and embryoids candevelop. Calli are undifferentiated aggregates of cells. Type I is arelatively compact, organized and slow growing callus. Type II is asoft, friable and fast-growing one. Embryoids are aggregates exhibitingsome embryo-like structures. The embryoids are preferred for subsequentsteps to regenerating plants. Culture medium “D” is an embodiment ofmedium that follows the isolation medium and replaces it. Medium “D”promotes growth to an embryoid/callus. This medium comprises 6N1 saltsat ⅛ the strength of a basic stock solution, (major components) andminor components, plus 12 percent sucrose or, preferably 12 percentmaltose, 0.1 mg/l B1, 0.5 mg/l nicotinic acid, 400 mg/l proline and 0.5mg/l silver nitrate. Silver nitrate is believed to act as an inhibitorto the action of ethylene. Multi-cellular structures of approximately 50cells each generally arise during a period of 12 days to 3 weeks. Serialtransfer after a two week incubation period is preferred.

After the petri dish has been incubated for an appropriate period oftime, preferably two weeks, in the dark at a predefined temperature, araft bearing the dividing microspores is transferred serially to solidbased media which promotes embryo maturation. In an illustrativeembodiment, the incubation temperature is 30° C. and the mesh raftsupporting the embryoids is transferred to a 100 mm petri dishcontaining the 6N1-TGR-4P medium, an “anther culture medium.” Thismedium contains 6N1 salts, supplemented with 0.1 mg/l TIBA, 12 percentsugar (sucrose, maltose or a combination thereof), 0.5 percent activatedcharcoal, 400 mg/l proline, 0.5 mg/l B, 0.5 mg/l nicotinic acid, and 0.2percent GELRITE™ (solidifying agent) and is capable of promoting thematuration of the embryoids. Higher quality embryoids, that is,embryoids which exhibit more organized development, such as better shootmeristem formation without precocious germination were typicallyobtained with the transfer to full strength medium compared to thoseresulting from continuous culture using only, for example, the isolatedmicrospore culture (IMC) Medium “D.” The maturation process permits thepollen embryoids to develop further in route toward the eventualregeneration of plants. Serial transfer occurs to full strengthsolidified 6N1 medium using either the nylon raft, the TRANSWELL®membrane or bilayer plates, each one requiring the movement ofdeveloping embryoids to permit further development into physiologicallymore mature structures.

In an especially preferred embodiment, microspores are isolated in anisolation media comprising about 6 percent maltose, cultured for abouttwo weeks in an embryoid/calli induction medium comprising about 12percent maltose and then transferred to a solid medium comprising about12 percent sucrose.

At the point of transfer of the raft after about two weeks incubation,embryoids exist on a nylon support. The purpose of transferring the raftwith the embryoids to a solidified medium after the incubation is tofacilitate embryo maturation. Mature embryoids at this point areselected by visual inspection indicated by zygotic embryo-likedimensions and structures and are transferred to the shoot initiationmedium. It is preferred that shoots develop before roots, or that shootsand roots develop concurrently. If roots develop before shoots, plantregeneration can be impaired. To produce solidified media, the bottom ofa petri dish of approximately 100 mm is covered with about 30 ml of 0.2percent GELRITE™ (solidifying agent) solidified medium. A sequence ofregeneration media are used for whole plant formation from theembryoids.

During the regeneration process, individual embryoids are induced toform plantlets. The number of different media in the sequence can varydepending on the specific protocol used. Finally, a rooting medium isused as a prelude to transplanting to soil. When plantlets reach aheight of about 5 cm, they are then transferred to pots for furthergrowth into flowering plants in a greenhouse by methods well known tothose skilled in the art.

Plants have been produced from isolated microspore cultures by methodsdisclosed herein, including self-pollinated plants. The rate of embryoidinduction was much higher with the synergistic preculture treatmentconsisting of a combination of stress factors, including a carbon sourcewhich can be capable of inducing starvation, a cold temperature andcolchicine, than has previously been reported. An illustrativeembodiment of the synergistic combination of treatments leading to thedramatically improved response rate compared to prior methods, is atemperature of about 10° C., mannitol as a carbon source, and 0.05percent colchicine.

The inclusion of ascorbic acid, an anti-oxidant, in the isolation mediumis preferred for maintaining good microspore viability. However, thereseems to be no advantage to including mineral salts in the isolationmedium. The osmotic potential of the isolation medium was maintainedoptimally with about 6 percent sucrose, although a range of 2 percent to12 percent is within the scope of this invention.

In an embodiment of the embryoid/callus organizing media, mineral saltsconcentration in IMC Culture Media “D” is (⅛×), the concentration whichis used also in anther culture medium. The 6N1 salts major componentshave been modified to remove ammonium nitrogen. Osmotic potential in theculture medium is maintained with about 12 percent sucrose and about 400mg/l proline. Silver nitrate (0.5 mg/l) was included in the medium tomodify ethylene activity. The preculture media is further characterizedby having a pH of about 5.7 to 6.0. Silver nitrate and vitamins do notappear to be crucial to this medium but do improve the efficiency of theresponse.

Whole anther cultures can also be used in the production ofmonocotyledonous plants from a plant culture system. There are somebasic similarities of anther culture methods and microspore culturemethods with regard to the media used. A difference from isolatedmicrospore cultures is that undisrupted anthers are cultured, so that asupport, e.g. a nylon mesh support, is not needed. The first step indeveloping the anther cultures is to incubate tassels at a coldtemperature. A cold temperature is defined as less than about 25° C.More specifically, the incubation of the tassels is preferably performedat about 10° C. A range of 8 to 14° C. is also within the scope of theinvention. The anthers are then dissected from the tassels, preferablyafter surface sterilization using forceps, and placed on solidifiedmedium. An example of such a medium is designated by the inventors as6N1-TGR-P4.

The anthers are then treated with environmental conditions that arecombinations of stresses that are capable of diverting microspores fromgametogenesis to embryogenesis. It is believed that the stress effect ofsugar alcohols in the preculture medium, for example, mannitol, isproduced by inducing starvation at the predefined temperature. In oneembodiment, the incubation pretreatment is for about 14 days at 10C. Itwas found that treating the anthers in addition with a carbon structure,an illustrative embodiment being a sugar alcohol, preferably, mannitol,produces dramatically higher anther culture response rates as measuredby the number of eventually regenerated plants, than by treatment witheither cold treatment or mannitol alone. These results are particularlysurprising in light of teachings that cold is better than mannitol forthese purposes, and that warmer temperatures interact with mannitolbetter.

To incubate the anthers, they are floated on a preculture medium whichdiverts the microspores from gametogenesis, preferably on a mannitolcarbon structure, more specifically, 0.3 M of mannitol plus 50 mg/l ofascorbic acid. 3 ml is about the total amount in a dish, for example, atissue culture dish, more specifically, a 60 mm petri dish. Anthers areisolated from about 120 spikelets for one dish yields about 360 anthers.

Chromosome doubling agents can be used in the preculture media foranther cultures. Several techniques for doubling chromosome number(Jensen, 1974; Wan et al., 1989) have been described. Colchicine is oneof the doubling agents. However, developmental abnormalities arisingfrom in vitro cloning are further enhanced by colchicine treatments, andprevious reports indicated that colchicine is toxic to microspores. Theaddition of colchicine in increasing concentrations during mannitolpretreatment prior to anther culture and microspore culture has achievedimproved percentages.

An illustrative embodiment of the combination of a chromosome doublingagent and preculture medium is one which contains colchicine. In aspecific embodiment, the colchicine level is preferably about 0.05percent. The anthers remain in the mannitol preculture medium with theadditives for about 10 days at 10° C. Anthers are then placed onmaturation media, for example, that designated 6N1-TGR-P4, for 3 to 6weeks to induce embryoids. If the plants are to be regenerated from theembryoids, shoot regeneration medium is employed, as in the isolatedmicrospore procedure described in the previous sections. Otherregeneration media can be used sequentially to complete regeneration ofwhole plants.

The anthers are then exposed to embryoid/callus promoting medium, forexample, that designated 6N1-TGR-P4 to obtain callus or embryoids. Theembryoids are recognized by identification visually of embryonic-likestructures. At this stage, the embryoids are transferred serially to aseries of regeneration media. In an illustrative embodiment, the shootinitiation medium comprises BAP (6-benzyl-amino-purine) and NAA(naphthalene acetic acid). Regeneration protocols for isolatedmicrospore cultures and anther cultures are similar.

B. Other Cultures and Regeneration

The present invention contemplates a corn plant regenerated from atissue culture of an inbred (e.g. GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU) or hybrid plant(DK706, DK446, DK474, DK642, DK604, DK560, DK566, DK442, DK527, DK626)of the present invention. As is well known in the art, tissue culture ofcorn can be used for the in vitro regeneration of a corn plant. By wayof example, a process of tissue culturing and regeneration of corn isdescribed in European Patent Application, publication 160,390, thedisclosure of which is incorporated by reference. Corn tissue cultureprocedures are also described in Green & Rhodes (1982) and Duncan etal., (1985). The study by Duncan indicates that 97 percent of culturedplants produced calli capable of regenerating plants. Subsequent studieshave shown that both inbreds and hybrids produced 91 percent regenerablecalli that produced plants.

Other studies indicate that non-traditional tissues are capable ofproducing somatic embryogenesis and plant regeneration. See, e.g.,Songstad et al. (1986), and Conger et al. (1987), the disclosures ofwhich are incorporated herein by reference.

Briefly, by way of example, to regenerate a plant of this invention,cells are selected following growth in culture. Where employed, culturedcells are preferably grown either on solid supports or in the form ofliquid suspensions as set forth above. In either instance, nutrients areprovided to the cells in the form of media, and environmental conditionsare controlled. There are many types of tissue culture media comprisingamino acids, salts, sugars, hormones and vitamins. Most of the mediaemployed to regenerate inbred and hybrid plants have some similarcomponents, the media differ in the composition and proportions of theiringredients depending on the particular application envisioned. Forexample, various cell types usually grow in more than one type of media,but exhibit different growth rates and different morphologies, dependingon the growth media. In some media, cells survive but do not divide.Various types of media suitable for culture of plant cells have beenpreviously described and discussed above.

An exemplary embodiment for culturing recipient corn cells in suspensioncultures includes using embryogenic cells in Type II (Armstrong & Green,1985; Gordon-Kamm et al., 1990) callus, selecting for small (10 to 30μ)isodiametric, cytoplasmically dense cells, growing the cells insuspension cultures with hormone containing media, subculturing into aprogression of media to facilitate development of shoots and roots, andfinally, hardening the plant and readying it metabolically for growth insoil.

Meristematic cells (i.e., plant cells capable of continual cell divisionand characterized by an undifferentiated cytological appearance,normally found at growing points or tissues in plants such as root tips,stem apices, lateral buds, etc.) can be cultured.

Embryogenic calli are produced (Gordon-Kamm et al., 1990). Specifically,plants from hybrids produced from crossing an inbred of the presentinvention with another inbred are grown to flowering in a greenhouse.Explants from at least one of the following F₁ tissues: the immaturetassel tissue, intercalary meristems and leaf bases, apical meristems,and immature ears are placed in an initiation medium which contain MSsalts, supplemented with thiamine, agar, and sucrose. Cultures areincubated in the dark at about 23° C. All culture manipulations andselections are performed with the aid of a dissecting microscope.

After about 5 to 7 days, cellular outgrowths are observed from thesurface of the explants. After about 7 to 21 days, the outgrowths aresubcultured by placing them into fresh medium of the same composition.Some of the intact immature embryo explants are placed on fresh medium.Several subcultures later (after about 2 to 3 months) enough material ispresent from explants for subdivision of these embryogenic calli intotwo or more pieces.

Callus pieces from different explants are not mixed. After furthergrowth and subculture (about 6 months after embryogenic callusinitiation), there are usually between 1 and 100 pieces derivedultimately from each selected explant. During this time of cultureexpansion, a characteristic embryogenic culture morphology develops as aresult of careful selection at each subculture. Any organized structuresresembling roots or root primordia are discarded. Material known fromexperience to lack the capacity for sustained growth is also discarded(translucent, watery, embryogenic structures). Structures with a firmconsistency resembling at least in part the scutulum of the in vivoembryo are selected.

The callus is maintained on agar-solidified MS-type media. A preferredhormone is 2,4-D. Visual selection of embryo-like structures is done toobtain subcultures. Transfer of material other than that displayingembryogenic morphology results in loss of the ability to recover wholeplants from the callus. Some calli exhibit somaclonal variation. Theseare phenotypic changes appearing in culture.

Cell suspensions are prepared from the calli by selecting cellpopulations that appear homogeneous macroscopically. A portion of thefriable, rapidly growing embryogenic calli is inoculated into MS Medium.The calli in medium are incubated at about 27° C. on a gyrotary shakerin the dark or in the presence of low light. The resultant suspensionculture is transferred about once every seven days by taking about 5 to10 ml of the culture and introducing this inoculum into fresh medium ofthe composition listed above.

For regeneration, embryos which appear on the callus surface areselected and regenerated into whole plants by transferring theembryogenic structures into a sequence of solidified media which includedecreasing concentrations of 2,4-D or other auxins. Other hormones whichcan be used in the media include dicamba, NAA, ABA, BAP, and 2-NCA. Thereduction is relative to the concentration used in culture maintenancemedia. Plantlets are regenerated from these embryos by transfer to ahormone-free medium, subsequently transferred to soil, and grown tomaturity.

Progeny are produced by taking pollen and selfing, backcrossing orsibling regenerated plants by methods well known to those skilled in thearts. Seeds are collected from the regenerated plants.

XIX. Processes of Preparing Corn Plants and the Corn Plants Produced bySuch Processes

The present invention also provides a process of preparing a novel cornplant and a corn plant produced by such a process. In accordance withsuch a process, a first parent corn plant is crossed with a secondparent corn plant wherein at least one of the first and second cornplants is the inbred corn plant GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU. In one embodiment,a corn plant prepared by such a process is a first generation F₁ hybridcorn plant prepared by a process wherein both the first and secondparent corn plants are inbred corn plants.

Corn plants (Zea mays L.) can be crossed by either natural or mechanicaltechniques. Natural pollination occurs in corn when wind blows pollenfrom the tassels to the silks that protrude from the tops of theincipient ears. Mechanical pollination can be effected either bycontrolling the types of pollen that can blow onto the silks or bypollinating by hand.

In a preferred embodiment, crossing comprises the steps of:

-   -   (a) planting in pollinating proximity seeds of a first and a        second parent corn plant, and preferably, seeds of a first        inbred corn plant and a second, distinct inbred corn plant;    -   (b) cultivating or growing the seeds of the first and second        parent corn plants into plants that bear flowers;    -   (c) emasculating flowers of either the first or second parent        corn plant, i.e., treating the flowers so as to prevent pollen        production, in order to produce an emasculated parent corn        plant;    -   (d) allowing natural cross-pollination to occur between the        first and second parent corn plant;    -   (e) harvesting seeds produced on the emasculated parent corn        plant; and, where desired,    -   (f) growing the harvested seed into a corn plant, or preferably,        a hybrid corn plant.

Parental plants are planted in pollinating proximity to each other byplanting the parental plants in alternating rows, in blocks or in anyother convenient planting pattern. Plants of both parental parents arecultivated and allowed to grow until the time of flowering.Advantageously, during this growth stage, plants are in general treatedwith fertilizer and/or other agricultural chemicals as consideredappropriate by the grower.

At the time of flowering, in the event that plant GMLEA, 6F905, 91CSV-1,91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU, isemployed as the male parent, the tassels of the other parental plant areremoved from all plants employed as the female parental plant. Thedetasseling can be achieved manually but also can be done by machine ifdesired.

The plants are then allowed to continue to grow and naturalcross-pollination occurs as a result of the action of wind, which isnormal in the pollination of grasses, including corn. As a result of theemasculation of the female parent plant, all the pollen from the maleparent plant, e.g., GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1,85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU, is available forpollination because tassels, and thereby pollen bearing flowering parts,have been previously removed from all plants of the inbred plant beingused as the female in the hybridization. Of course, during thishybridization procedure, the parental varieties are grown such that theyare isolated from other corn fields to prevent any accidentalcontamination of pollen from foreign sources. These isolation techniquesare well within the skill of those skilled in this art.

Both of the parent inbred plants of corn are allowed to continue to growuntil maturity, but only the ears from the female inbred parental plantsare harvested to obtain seeds of a novel F₁ hybrid. The novel F₁ hybridseed produced can then be planted in a subsequent growing season withthe desirable characteristics in terms of F₁ hybrid corn plantsproviding improved grain yields and the other desirable characteristicsdisclosed herein, being achieved.

Alternatively, in another embodiment, both first and second parent cornplants can come from the same inbred corn plant, i.e., from the inbredsdesignated, separately, GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1,85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU. Thus, any corn plantproduced using a process of the present invention and inbred corn plantGMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1,01IBH2, NL054B or FBMU, is contemplated by this invention. As usedherein, crossing can mean selfing, backcrossing, crossing to another orthe same inbred, crossing to populations, and the like. All corn plantsproduced using the present inbred corn plants, i.e., GMLEA, 6F905,91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B orFBMU, as a parent are within the scope of this invention.

The utility of the inbred plants GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B and FBMU, also extends tocrosses with other species. Commonly, suitable species will be of thefamily Graminaceae, and especially of the genera Zea, Tripsacum, Coix,Schlerachne, Polytoca, Chionachne, and Trilobachne, of the tribeMaydeae. Of these, Zea and Tripsacum, are most preferred. Potentiallysuitable for crosses with GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1,85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B and FBMU can be the variousvarieties of grain sorghum, Sorghum bicolor (L.) Moench.

A. F₁ Hybrid Corn Plant and Seed Production

Where the inbred corn plant GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU is crossed withanother, different, corn inbred, a first generation (F₁) corn hybridplant is produced. Both a F₁ hybrid corn plant and a seed of that F₁hybrid corn plant are contemplated as aspects of the present invention.

Inbreds GMLEA and 6F905 have been used to prepare an F₁ hybrid cornplant, designated DK706; inbreds 91CSV-1 and 01ASB1 have been used toprepare an F₁ hybrid corn plant, designated DK446; inbreds WDAQ2 and01IBH2 have been used to prepare an F₁ hybrid corn plant, designatedDK604; inbreds 01IBH2 and FBMU have been used to prepare an F₁ hybridcorn plant, designated DK527; inbred 91DFA-5 has been used to prepare anF₁ hybrid corn plant, designated DK474; inbred WDDQ1 has been used toprepare an F₁ hybrid corn plant, designated DK642; inbred 85DGD1 hasbeen used to prepare an F₁ hybrid corn plant, designated DK560; inbredPHEI4 has been used to prepare an F₁ hybrid corn plant, designatedDK566; inbred 01IBH2 has additionally been used to prepare the F₁ hybridcorn plant designated DK442; and inbred NL054B has been used to preparean F₁ hybrid corn plant, designated DK626.

The goal of a process of producing an F₁ hybrid is to manipulate thegenetic complement of corn to generate new combinations of genes whichinteract to yield new or improved traits (phenotypic characteristics). Aprocess of producing an F₁ hybrid typically begins with the productionof one or more inbred plants. Those plants are produced by repeatedcrossing of ancestrally related corn plants to try and concentratecertain genes within the inbred plants. The production of inbreds GMLEA,6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2,NL054B and FBMU has been set forth hereinbefore.

Corn has a diploid phase which means two conditions of a gene (twoalleles) occupy each locus (position on a chromosome). If the allelesare the same at a locus, there is said to be homozygosity. If they aredifferent, there is said to be heterozygosity. In a completely inbredplant, all loci are homozygous. Because many loci when homozygous aredeleterious to the plant, in particular leading to reduced vigor, lesskernels, weak and/or poor growth, production of inbred plants is anunpredictable and arduous process. Under some conditions, heterozygousadvantage at some loci effectively bars perpetuation of homozygosity.

Inbreeding requires coddling and sophisticated manipulation by humanbreeders. Even in the extremely unlikely event inbreeding rather thancrossbreeding occurred in natural corn, achievement of completeinbreeding cannot be expected in nature due to well known deleteriouseffects of homozygosity and the large number of generations the plantwould have to breed in isolation. The reason for the breeder to createinbred plants is to have a known reservoir of genes whose gametictransmission is at least somewhat predictable.

The development of inbred plants generally requires at least about 5 to7 generations of selfing. Inbred plants are then cross-bred in anattempt to develop improved F₁ hybrids. Hybrids are then screened andevaluated in small scale field trials. Typically, about 10 to 15phenotypic traits, selected for their potential commercial value, aremeasured. A selection index of the most commercially important traits isused to help evaluate hybrids. FACT, an acronym for Field AnalysisComparison Trial (strip trials), is an on-farm testing program employedby DEKALB Plant Genetics to perform the final evaluation of thecommercial potential of a product.

During the next several years, a progressive elimination of hybridsoccurs based on more detailed evaluation of their phenotype. Eventually,strip trials (FACT) are conducted to formally compare the experimentalhybrids being developed with other hybrids, some of which werepreviously developed and generally are commercially successful. That is,comparisons of experimental hybrids are made to competitive hybrids todetermine if there was any advantage to further commercial developmentof the experimental hybrids. Examples of such comparisons are presentedin XVII, Section B, hereinbelow.

When the inbred parental plant, i.e., GMLEA, 6F905, 91CSV-1, 91DFA-5,WDAQ2, WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B or FBMU, is crossedwith another inbred plant to yield a hybrid (such as the hybrids DK706,DK446, DK474, DK642, DK604, DK560, DK566, DK442, DK527, DK626), theoriginal inbred can serve as either the maternal or paternal plant. Formany crosses, the outcome is the same regardless of the assigned sex ofthe parental plants.

However, there is often one of the parental plants that is preferred asthe maternal plant because of increased seed yield and productioncharacteristics. Some plants produce tighter ear husks leading to moreloss, for example due to rot. There can be delays in silk formationwhich deleteriously affect timing of the reproductive cycle for a pairof parental inbreds. Seed coat characteristics can be preferable in oneplant. Pollen can be shed better by one plant. Other variables can alsoaffect preferred sexual assignment of a particular cross.

B. F₁ Hybrid Comparisons

As mentioned in Section A, hybrids are progressively eliminatedfollowing detailed evaluations of their phenotype, including formalcomparisons with other commercially successful hybrids. Strip trials areused to compare the phenotypes of hybrids grown in as many environmentsas possible. They are performed in many environments to assess overallperformance of the new hybrids and to select optimum growing conditions.Because the corn is grown in close proximity, environmental factors thataffect gene expression, such as moisture, temperature, sunlight andpests, are minimized. For a decision to be made that a hybrid is worthmaking commercially available, it is not necessary that the hybrid bebetter than all other hybrids. Rather, significant improvements must beshown in at least some traits that would create improvements in someniches.

Examples of such comparative data are set forth hereinbelow in Tables 32through 41, which present a comparison of performance data for thehybrids DK706, DK446, DK474, DK642, DK604, DK560, DK566, DK442, DK527and DK626, versus several other selected hybrids of commercial value.

In another aspect, the present invention provides a genetic complementof a plant of this invention. In one embodiment, therefore, the presentinvention contemplates an inbred genetic complement of the inbred cornplants designated, separately, GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B and FBMU. In anotherembodiment, the present invention contemplates a hybrid geneticcomplement formed by the combination of a haploid genetic complementfrom GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2, WDDQ1, 85DGD1, PHEI4,01ASB1, 01IBH2, NL054B or FBMU and another haploid genetic complement.Means for determining a genetic complement are well-known in the art.

As used herein, the phrase “genetic complement” means an aggregate ofnucleotide sequences, the expression of which sequences defines thephenotype of a corn plant or a cell or tissue of that plant. By way ofexample, a corn plant is genotyped to determine the array of theinherited markers it possesses. Markers are alleles at a single locus.They are preferably inherited in codominant fashion so that the presenceof both alleles at a diploid locus is readily detectable, and they arefree of environmental variation, i.e., their heritability is 1. Thisgenotyping is preferably performed on at least one generation of thedescendant plant for which the numerical value of the quantitative traitor traits of interest are also determined. The array of single locusgenotypes is expressed as a profile of marker alleles, two at eachlocus. The marker allelic composition of each locus can be eitherhomozygous or heterozygous. Homozygosity is a condition where bothalleles at a locus are characterized by the same nucleotide sequence.Heterozygosity refers to different conditions of the gene at a locus.Markers that are used for purposes of this invention include restrictionfragment length polymorphisms (RFLPS) and isozymes.

A plant genetic complement can be defined by a genetic marker profilesthat can be considered “fingerprints” of a genetic complement. Forpurposes of this invention, markers are preferably distributed evenlythroughout the genome to increase the likelihood they will be near aquantitative trait loci (QTL) of interest (e.g., in tomatoes, Nienhuiset al., 1987). These profiles are partial projections of a sample ofgenes. One of the uses of markers in general is to exclude, oralternatively include, potential parents as contributing to offspring.

Phenotypic traits characteristic of the expression of a geneticcomplement of this invention are distinguishable by electrophoreticseparation of DNA sequences cleaved by various restrictionendonucleases. Those traits (genetic markers) are termed RFLP(restriction fragment length polymorphisms).

Restriction fragment length polymorphisms (RFLPs) are geneticdifferences detectable by DNA fragment lengths, typically revealed byagarose gel electrophoresis, after restriction endonuclease digestion ofDNA. There are large numbers of restriction endonucleases available,characterized by their nucleotide cleavage sites and their source, e.g.,Eco RI. Variations in RFLPs result from nucleotide base pair differenceswhich alter the cleavage sites of the restriction endonucleases,yielding different sized fragments.

Means for performing RFLP analyses are well known in the art.Restriction fragment length polymorphism analyses reported herein wereconducted by Linkage Genetics. This service is available to the publicon a contractual basis. Probes were prepared to the fragment sequences,these probes being complementary to the sequences thereby being capableof hybridizing to them under appropriate conditions well known to thoseskilled in the art. These probes were labelled with radioactive isotopesor fluorescent dyes for ease of detection. After the fragments wereseparated by size, they were identified by the probes. Hybridizationwith a unique cloned sequence permits the identification of a specificchromosomal region (locus). Because all alleles at a locus aredetectable, RFLPs are codominant alleles, thereby satisfying a criteriafor a genetic marker. They differ from some other types of markers, e.g,from isozymes, in that they reflect the primary DNA sequence, they arenot products of transcription or translation. Furthermore, differentRFLP genetic marker profiles result from different arrays of restrictionendonucleases.

The RFLP genetic marker profile of each of the parental inbreds andexemplary resultant hybrids were determined. Because an inbred isessentially homozygous at all relevant loci, an inbred should, in almostall cases, have only one allele at each locus. In contrast, a diploidgenetic marker profile of a hybrid should be the sum of those parents,e.g., if one inbred parent had the allele A at a particular locus, andthe other inbred parent had B, the hybrid is AB by inference.

RFLP genetic marker profiles of GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B and FBMU, are is presentedin Tables 52 through 63.

Another aspect of this invention is a plant genetic complementcharacterized by a genetic isozyme typing profile. Isozymes are forms ofproteins that are distinguishable, for example, on starch gelelectrophoresis, usually by charge and/or molecular weight. Thetechniques and nomenclature for isozyme analysis are described in,Stuber et al. (1988), which is incorporated by reference.

A standard set of loci can be used as a reference set. Comparativeanalysis of these loci is used to compare the purity of hybrid seeds, toassess the increased variability in hybrids compared to inbreds, and todetermine the identity of seeds, plants, and plant parts. In thisrespect, an isozyme reference set can be used to develop genotypic“fingerprints.”

Tables 64 through 75 list the identifying numbers of the alleles atisozyme loci types. Tables 64 through 75 represent the exemplary geneticisozyme typing profiles for GMLEA, 6F905, 91CSV-1, 91DFA-5, WDAQ2,WDDQ1, 85DGD1, PHEI4, 01ASB1, 01IBH2, NL054B and FBMU, respectively.
